Application: krunner (0.1)
KDE Platform Version: 4.8.1 (4.8.1) "release 481"
Qt Version: 4.8.0
Operating System: Linux 3.2.9-2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

My laptop zombied because of I lauched too many applications. then I mannualy powered it off by holding poweroff button enough long.

then I restarted it. KDE goes back to default wallpaper. (I don't know why, sometimes it happens.)

And nepomuk _MUST_ rescan my filesystem (don't know why), as I used Btrfs as my filesystem, it takes long time to do the sync work.

Because CPU usage is so high that Krunner can't be automatically started (I have experienced that before).

I opened a konsole, start krunner from there. then in a few minutes, it crashed.

- Unusual behavior I noticed:

Not at all. actually my laptop lags and I concentrated my mind on iotop to see if it's nepomuk.

But I'm sure if nepomuk is scanning your filesystem, and ate too much memories or cpu, krunner will randomly crash.

- Custom settings of the application:

default settings.

The crash can be reproduced some of the time.
